Drills Kodex K-97 ParaPulpal ( Common for all Parapulpal Pins Coltene )

A parapulpal pin in dentistry refers to a small metal pin that is placed in the dentin, near the pulp, to enhance the retention and support of a dental restoration. These pins can be used in situations where tooth structure is compromised and there's not enough retention for restorations like fillings or crowns.

Here's a brief overview of how they're used:

1. Preparation: After removing decay and preparing the tooth for the restoration, the dentist drills a small hole in the dentin where the pin will be placed.

2. Insertion: The pin is then threaded or tapped into the hole. Once in place, it provides additional support for the dental material that will be used to restore the tooth.

3. Restoration: Dental material (like amalgam, composite, etc.) is then placed over and around the pin, effectively locking it in place and using it as an anchor.

It's essential for the pin to be placed in a manner that avoids the pulp (the nerve and blood vessels in the center of the tooth) to prevent any possible injury. Proper placement ensures that the restoration is both functional and comfortable for the patient.

However, with advancements in dental materials and techniques, the use of parapulpal pins has become less common. Modern adhesive dentistry techniques often allow for sufficient retention of restorations without the need for such pins. Still, they may be used in certain situations where added support is required.
